Abstract (en)

[origin: DE19645650C1] The cutting head is fitted to a support arm which positions it into the cutting positions. A steel housing has a motor (18) in the top end, under the mounting flange (5) for the support arm. Three in-line pinions (20,22,21a) form a reduction gear train down the housing. The last gear carries the double axle stubs (21) with cutting heads at each end. The whole housing is sealed against ingress of grit. The steel housing has two parallel side flanges in which the support bearings for the gearwheels are fitted. The size of the housing is determined by the diameter of the largest, middle gearwheel.
